NIFTI_STATS(1)							   User Commands						    NIFTI_STATS(1)

NAME

       nifti_stats - compute NIfTI statistical functions

SYNOPSIS

       nifti_stats [-q|-d|-1|-z] value CODE [p1 p2 p3]

DESCRIPTION

       nifti_stats  supports several distributions (normal, uniform, logistic, chi, etc.) and calculates density or cummulative distribution func-
       tion (and many more). Values are printed to stdout and can be piped to other tools.

       value can be a single number or in the form bot:top:step.
	      default ==> output p = Prob(statistic < val).

       -q     ==> output is 1-p.

       -d     ==> output is density.

       -1     ==> output is x such that Prob(statistic < x) = val.

       -z     ==> output is z such that Normal cdf(z) = p(val).

       -h     ==> output is z such that 1/2-Normal cdf(z) = p(val).

       Allowable CODEs:

       CORREL, TTEST, FTEST, ZSCORE, CHISQ, BETA, BINOM, GAMMA, POISSON, NORMAL, FTEST_NONC, CHISQ_NONC, LOGISTIC, LAPLACE,  UNIFORM,  TTEST_NONC,
       WEIBULL, CHI, INVGAUSS, EXTVAL, PVAL, LOGPVAL and LOG10PVAL

	      Following CODE are distributional parameters, as needed.

       Results are written to stdout, 1 number per output line.

EXAMPLE

       Piping output into AFNI program 1dplot:

	      nifti_stats -d 0:4:.001 INVGAUSS 1 3 | 1dplot -dx 0.001 -stdin

NAME

       nifti - IO libraries and tools for the NIFTI-1 data format

DESCRIPTION

       The  NIfTI-1  data  format  is  a binary file format for storing medical image data, e.g. magnetic resonance image (MRI) and functional MRI
       (fMRI) brain images.

       The NIfTI format is an extension of the widely used ANALYZE 7.5 format. The goals of this modified data format are (1) to  add  information
       to the header that will be useful for functional neuroimaging data analysis and display. These additions include:

	      - More basic data types.
	      - Two affine transformations to specify voxel coordinates.
	      - "Intent" codes and parameters to describe the meaning of the data.
	      - Affine scaling of the stored data values to their "true" values.
	      - Optional storage of the header and image data in one file (.nii).

       And (2) To maintain compatibility with non-NIFTI-aware ANALYZE 7.5 compatible software (i.e., such a program should be able to do something
       useful with a NIFTI-1 dataset -- at least, with one stored in a traditional .img/.hdr file pair).

       The NIfTI library package consists of two libraries:

       znzlib -- low level library for handling read/write of compressed files.

       niftilib -- core i/o routines for reading and writing nifti-1 format files. Primarily routines to  read/write  and  manipulate  the  header
       field information, including orientation matrices.  Volume-wise, timecourse-wise, access to image data.
